Did more checking on Encore at gunstoredid some measuring. They will work with a longer and
a real heavy barrel and a weighted thumbhole
buttstock.And long barrel to get weight and get the blast away from shooter. If I did one I'd make it 20
pounds at least. they will handle moderate pressure
with heavy barrel, muzzle same size as breech, so
that it will hold rifle type loadings.barrel would have to
be alloy barrel like big bore ones we have on Savage.Ed.
